ROLLING SCREEN.

Specification of Letters Patent.

Patented Sept. 28, 1920.

Application filed November 12, 1918. Serial No. 262,186.

new and novel device of this character whichmay be attached on the outside or a window frame and rolled up as desired, and the screen being attended'with. certain devices attachable to the window frame whereby it may be held in full extended position or various partially extended positions.

The invention isi'urther designed to'provide a screen of this design having a spring actuated roller which tends normally to keep the spring rolled thereon and a novel bottom rail attached to the bottom end of the spring which is engaged by, the aforementioned devices. 1

Other and further purposes for which the invention is designed are made to appear in the following detail description.

A specific embodiment has been employed to. illustrate the invention, but to this embodiment it is not to be restricted. Actual reduction to practice may show certain desirable changes or alterations to be of ad-' vantage, and the right is claimed to make any which do not deviate from the scope of the invention as claimed.

Fig. 10 is a vertical transverse sectional View showing the manner of connection of the screen mesh with the lower bar.

The invention is illustrated as applied to the window frame A, and it comprises the roller supports 1, the roller 2 and the screen or wire mesh 3. The two supports 1 are identical with the exception of having the one prepared to hold the flatted stud of the roller while the other supports the round stud and either one consists of an L-shaped supporting member 3', the shorter leg of which is provided with appropriate holes to permit the members being attached to the window frame. In the longer leg of the L- shaped member a longitudinal slot 4 is formed, and through this slot there passes the tongue 5 of the roller engaging member 6. This roller engaging member 6 receives either the round or flatted stud of the roller, depending on which side of the window it is designed for attachment, and at the free end its tongue is provided with the lateral projections 7 which lie against the opposite face of the L-shaped member from that against which the major portion of the roller engaging member 6 lies, the tongue 5 being offset enough to permit this arrangement of these two portions of the roller engaged member. Farther than the tongue 5 and its lateral projection 7, the roller engaging member is formed with a hook member 8 on its upper edge which hangs over the upper edge of the longer leg of the L- shaped member 3.

Both roller engaging members as the result of the particular construction disclosed, are so supported by the L-shaped members that they may be adjusted toward or away from the window frame, the limits of this adjustment being prescribed by the length of the slots 4.

The roller 2 employed comprises a tubular member 9 closed at one end by the plug 10 and the other end by the disk 11. Fixed in therplug 10 there is the round stud 12 of the roller which turns in the bracket engaging member 6 prepared to receive it. Loosely mounted in the disk 11, there is a ilatted stud l3 and interior to the roller, this flatted stud has attached to it one end of the spring 14, the other end of said spring being connected with the plug 10. In order to provide the attachment of the screen or wire mesh 3 to the roller, there is provided a strip 15 which extends the full length of the tubular member 9 and is secured to the ends thereof in any appropriate manner, preferably as shown. One end of the screen or mesh is inserted between the roller, and this strip and the end thus inserted is bent back so that it practically hooks over the strip, as shown, thus firmly securing the screen to the roller.

At the end remote from the roller, the screen is attached to a bar or rail 16 which extends beyond either side of the screen, so that the said extending ends may be engaged by the L-shaped members 17 which are pivotallymounted on either side of the window frame by means of suitable screws 18. The longer legs of the Lshaped members stand normally parallel to the window sill and have their free ends coiled as shown to provide hand grips 19, and these legs are intended to stand behind the screen so the hand grips may be reached from the inside of the window, the screen itself, of course, being hung on the outside of the window. The shorter legs ofthe L-shaped members 17 have the U-shaped members 20 formed at their ends and these U-shaped members 20 straddle and frictionally engage the extending ends of the bar or rail 16.

r The hand grip 21 is attached to the rail inside of the window to permit the screen being lowered-and raised with the spring 14 of the roller under control.

At intermediate points on the vertical stiles 0f the window frame, intermediate stops 22 are provided. These stops are formed with the hooked ends 23 and are supported on the-vertical stiles by suitable screws 24:, the screws passing through the stops at points intermediate between the ends of the latter, so that the tails 25 may lie between the screen and the window frame when the stops are positioned horizontally as they are to permit the bottom rail 16 to pass by them. When thestops 22 are moved to vertical position, the hooked ends 23 stand at the top and intercept the extending end of the rail 16 to prevent the screen being raised higher than any pair of stops'so positioned.

It will be observed that the intermediate stops 22 perform a dual function. Turned into the horizontal position shown in Fig. 1,

tended position and the intermediate stops 22 intheir normal positions which are horizontal. Desiring to raise the screen, the hand grips 19 are depressed, whereupon the U-shaped members 20 are moved outwardly, thus freeing the rail 16, whereupon the spring 1 1 will operate to roll the screen 3 upon the roller 2,.thus lifting the rail 16. If it is desired to stop the screen at any point between the full extended position and the fully raised position, the intermediate stops at the desired point are moved to verticalpositions, whereupon the hooked ends 23 intercept and engage the extending ends of the rail 16. The screen may be raised to the next higher position by turning the'intermediate stops just above the previous stops to avertical position and returning said previous stops to a horizontal position, and this operation maybe repeated until the screen is fully raised. The intermediate stops may bethrown into the dethe construction and operation of the invention will be appreciated, and further description is therefore omitted.

The invention having been described, what is claimed as'new and useful is:

1. In a device of the kind described, a spring actuated roller, a wire screen carried thereon, a transverse rail attached to the screen at its lower end, means for supporting the spring actuated roller in a window frame, intermediate stops for pivotal attachment to the vertical stiles of the window frame, each of said stops consisting of a tail portion and a hook end opposite the tail portion, thetail portions overlapping the sides of the screen to hold the same against the window frame when the stops are horizontally disposed, the bottom rail extending laterally'beyond the sides of the screen, and latching elements for pivotal connection to the window frame adjacent the sill and having means for engaging the extending ends of the bottom rail to hold the screen in lowered position, the intermediate stops being adapted for shifting into vertical positions when the hook ends may engage the said projecting ends of the rail to preclude raising of the screen higher than any two vertically disposed intermediate stops. 7

2. A rolling screen consisting of a spring actuated roller and means for mounting the same in a window frame, a wire mesh screen carried by the said roller, a rail connected with the screen at the end remote from the roller and projecting laterally beyond the side edges of the screen, and L-shaped members for pivotal mounting on the Window frame, one leg of each of said members being of U-shaped construction at its extremity for engagement over one of the projecting ends of the bottom rail, the remaining leg of each of said members lying normally in a horizontal plane and being disposed behind the screen between it and the Win- 10 (10W frame, whereby the L-shaped members may be shifted on their pivotal connections to engage the projecting ends of the bottom rail for release therefrom.

In testimony whereof I affix my signature. 15
